“…The cathodic cage plasma deposition (CCPD) was developed by Alves et al 1 and has been employed for depositing a variety of coatings on different substrates [1][2][3][4][5][6][7][8][9] . In the CCPD process, the samples are inserted on an alumina insulator disk that is located inside a cage with uniformly distributed round holes of fixed diameter, so that the plasma acts on the cage and not on the sample surface, avoiding possible defects that are commonly formed during conventional plasma deposition [1][2][3][4][5][6][7][8][9] .…”

Pulsed dc discharge in the presence of active screen for nitriding of high carbon steel

“…The dc plasma nitriding (DCPN) is a well-accepted industrial process for the improvement of surface properties such as hardness, wear and corrosion resistance, thus increasing the useful life of the treated piece [1][2][3][4] . It has several advantages over other nitriding techniques such as gas and salt bath nitriding.…”

Cathodic cage nitriding of AISI 409 ferritic stainless steel with the addition of CH4

“…It is used in the manufacture of nitric acid storage tanks, automobile accessories, domestic utensils, coins, elevator coatings and refrigerated cabinets 12 . In this study, we use the same plasma nitriding reactor, but with a modified experimental arrangement illustrated in Figure 1, called a cathodic cage 5,[13][14][15] , whose principle of operation is based on the hollow-cathode effect in the walls of the all holes.…”
